Type 2 diabetes mellitus management and body mass index: experiences with initiating insulin detemir in the a1chieve study.

INTRODUCTION: This sub-analysis of the A1chieve study aimed to examine the safety and efficacy of insulin detemir (IDet) initiation over 24 weeks in relation to baseline body mass index (BMI) in people with type 2 diabetes mellitus (T2DM). METHODS: A1chieve was a 24-week non-interventional study to assess the safety and efficacy of insulin analogs in routine practice. This sub-analysis included insulin-naïve patients who initiated IDet therapy based on their physicians' decision. Patients were stratified according to baseline BMI (Group I, <25.0 kg/m(2); Group II, 25.0 to <30.0 kg/m(2); Group III, 30.0 to <35.0 kg/m(2); Group IV ≥35.0 kg/m(2)). Safety and efficacy variables were assessed over 24 weeks. RESULTS: Overall, 10,650 insulin-naïve patients were included (3,045 patients in Group I, 4,186 patients in Group II, 2,365 patients in Group III, and 1,054 patients in Group IV). Four serious adverse drug reactions (SADRs) were reported. From baseline to Week 24, there was no statistically significant difference in the proportion of patients reporting overall hypoglycemia in Group I (4.0% vs. 4.4%), while a significant decrease in Group II (4.8% vs. 4.0%, p = 0.0335) and significant increases in Groups III and IV (3.3% vs. 5.4% and 3.4% vs. 7.0%, respectively, p < 0.001) were noted. The mean body weight increased from baseline to Week 24 in Group I (60.7 ± 8.4 vs. 61.8 ± 8.5 kg) and reduced in Groups II, III, and IV (74.5 ± 9.2 vs. 74.2 ± 9.2 kg, 87.4 ± 10.3 vs. 86.0 ± 9.8 kg, and 102.2 ± 14.3 vs. 100.1 ± 14.2 kg, respectively; all p < 0.001). Significant improvements were noted in glycemic parameters, systolic blood pressure, and lipids over 24 weeks, irrespective of baseline BMI status. CONCLUSION: IDet therapy was associated with improved glycemic control and a low number of SADRs. Greater weight loss was observed with higher BMI.
